Zii table cannot be updated.

I have index-ss.php And it has a search form in it,

search form




    <div class="search-form" style="display:none">

                    <section class="panel panel-success portlet-item">

                        <header class="panel-heading">Search</header>

                        <ul class="list-group alt">

                          <li class="list-group-item">


                            <div class="wide form">


                            <?php $form=$this->beginWidget('CActiveForm', array(

                                'action'=>Yii::app()->createUrl($this->route),

                                'method'=>'get',

                                'htmlOptions'=>array('class'=>'form-horizontal'),

                            )); ?>


                                <div class="form-group">

                                    <label class="col-sm-2 control-label">User</label>

                                    <div class="col-sm-10">

                                        <select class="form-control" name="User[username]" id="User_username">

                                            <option value="">--- Select ---</option>

                                            <?php

                                            $userList = Profile::model()->findAll(array('order'=>'firstname'));

                                            foreach ($userList as $value) {

                                                echo '<option value="'.$value->user['username'].'">'.$value['firstname'].' '.$value['lastname'].'</option>'; 

                                            }

                                            ?>

                                        </select>

                                    </div>

                                </div>


                                <div class="form-group">

                                    <label class="col-sm-2 control-label"><?php echo $form->label($model,'email'); ?></label>

                                    <div class="col-sm-10">

                                        <?php echo $form->textField($model,'email',array('size'=>60,'maxlength'=>128, 'class'=>'form-control')); ?>

                                    </div>

                                </div>


                                <div class="form-group">

                                    <label class="col-sm-2 control-label"><?php echo $form->label($model,'superuser'); ?></label>

                                    <div class="col-sm-10">

                                        <?php echo $form->dropDownList($model,'superuser',$model->itemAlias('AdminStatus'), array('class'=>'form-control')); ?>

                                    </div>

                                </div>


                                <div class="form-group">

                                    <label class="col-sm-2 control-label"><?php echo $form->label($model,'status'); ?></label>

                                    <div class="col-sm-10">

                                        <?php echo $form->dropDownList($model,'status',$model->itemAlias('UserStatus'), array('class'=>'form-control')); ?>

                                    </div>

                                </div>


                                <div class="form-group">

                                    <?php echo CHtml::submitButton(UserModule::t('Start Searching'), array('class'=>'btn btn-sm btn-primary')); ?>

                                </div>


                            <?php $this->endWidget(); ?>


                            </div><!-- search-form -->


                          </li>

                        </ul>

                    </section>

                  </div>



Then it would be pass onto a script above it.


	$('.search-form form').submit(function(){

	    $.fn.yiiGridView.update('user-grid', {

	        data: $(this).serialize()

	    });

      alert($(this).serialize());

	    return false;

	});

And pass it onto this table:


  $this->widget('zii.widgets.grid.CGridView', array(

              						'itemsCssClass'=>'table table-striped m-b-none b-b b-light',

              						'id'=>'user-grid',

              						'dataProvider'=>$model->search(),

              						'enableSorting'=>false,

              						'emptyText'=>'No entries found.',

              						'summaryText'=>'Showing {start}-{end} of {count} entries <span class="page-size-wrap">Display '.$pageSizeDropDown.' per page</span>',

              						'columns'=>array(

              							array(

              								'name' => 'username',

              								'header'=>'User',

              								'type'=>'raw',

              								'value' => 'CHtml::link("<strong>".UHtml::markSearch($data,"username")."</strong><br />".$data->email."<br />".$data->profile->firstname." ".$data->profile->lastname,array("admin/view","id"=>$data->id))',

                              'htmlOptions' => array('style' => 'width: 50%;'),

              							), ...etc

The table would show at first, but then when updated it will not change. It just shows the same table.
